Underwater propulsion device using air with high safety

摘要

The present invention relates to an underwater propulsion device using air with high safety, and more specifically, by using the air in the reservoir 100 to fix the thruster 300 to the user's waist, the propulsion force due to air discharge In addition, when a certain amount of air is consumed by the control unit 500 and the amount of air is less than the set value, a separate small-scale auxiliary thruster is additionally provided to prevent loss of propulsion by blocking air discharge. On the other hand, it is a useful invention that enables rapid movement through a structure that reduces the resistance to water and the solid fixing force of the reservoir.
